HARRY W. BROWN, OF SEATTLE, WASHINGTON.

MoNonAiL-ona.

T0 all whom it may concern:

Be it known that I, HARRY lV. BROWN, a citizen of the United States, and a resident ot' Seattle, in the county of King and' State of lVashington, have invented cert-ain new and useful Improvements in llulonorail-Cars, of which the following is a specification.

This invention relates to monorail cars,

and has Jfor its principal lobject to 'providey porting structure, with a car thereon. Fig.

2 is a sectional. View upon the line motv Fig. 1. 3 is an enlarged detail View ot one of the plates upon which the car springs are mounted.

Referring now more particularly to the drawings, reference character A, designates, in a general way, one of the ground supports for the track, consisting of the cross timber 1, supported upon the piles 2; the Vertical timber 3, secured to the said cross timber,

and the side braces 4:, the lower ends of.

which are secured to the said. cross timber and their upper ends bear against the angle irons 5, secured to the said `vert-ical timber 3.

The said Vertical timber may be further reinforced by the braces G. It will be, of course, understood that ground supports similar to that just described, occur at suitable interv- Vals, and upon the upper ends ofithe vertical timbers is the track proper, preferably ot the laminated form, as shown and which is indicated at 7. Upon the track7 is the rail 8, substantially of U shape, in cross section, as shown, and upon which the wheel 9 rests, the face of-the said wheel being slightly convex (see Fig. 2). The ends ot' the axle 10 are revolubly mounted in suitable journal bearings in the blocks 11, which slide Tertically within the recesses 12 in the casting 13, the saidreccsses being channeled in the direction ot' their length, as indicated by the dotted line in F ig. 1. cesses slide the plates 14, the extensions 15 of which slidably tit into the said channels,

as will be understood.v Upon the plates 14 are the studs 16 which project into the helical springs 17, the uppermost plate 1li being held in position by the cap 18, through which passes the threaded bolt 19. By the means described, the casting 13,with its associated parts, is yieldingly mounted upon the axles 10, Re'Volubly passing through the casting '13, from side to side, are the shafts '20, upon which are mounted the rollers 21. Entending downwardly from each side of the casting 13 are the members 22, which are joined together, at their bottoms, by the member 23.

Extending outwardly from one pair of the said members 22, are the projections 211, upon which are yieldingly mounted, as by means ot the springs 25, the blocks 26, through which blocks revolubly pass the axles 27 of the wheels 28, the upper pair ot which contact with the sides of the track 7, and the lower pair contact with the stringers 29, secured to the vvertical timber 3. Extending outwardly from the member 23 are the arms 30, the outer ends of which rare connected by the strip 31. Through the arms 30 ass the bolts 32, which are yieldingly held in the 'positions shown by the springs4 To the lower ends ot the said bolts are secured the -members 34, upon the upper side of which is the ball 34a which tits into a suitable socket in the boss 35, upon the lower side ofthe oar 36, in which-may bel the window 37, and trom'which downwardly extend the side boards 38.

lt may or may not be old in the art to employ a wheel substantially of the same formation as that shown at f), but which has a' rubber or other resilient face, adapted to run upon a flat faced rail; but the disadvantage ot such construction is apparent in that unnecessary .;trietion is created between the wheel and its rail, and especially' is this true in rounding curves. About thc same objections apply to the use of an ordinary double tlanged wheeljfor this purpose. It is clear that in my improved construction, two points of contact only exist between the wheel 9 and its rail 8, due tojvhich the friction between the wheel and its railis reduced to a minimum, and especially is this true when the ear is rounding a curve -in the track.A This reduction to a minimum foi the fric tion is more apparent when it is considered that but one wheel-dg), is used, in. conse quence of which any vertical movement of the ends of the axle 10 simply causes 4the convex face of the Wheel 9 to Wipe against the two contacting points of the rail 8,Witl1 out undue binding which, would, of course, occur to a greater or less extent if two such wheels were employed side by side on parallel tracks..

From the foregoing it is believed that the construction and operation of my device Will be fully understood by others, and,' While I have shown a particular form of car body, supporting structure and other details7 I am fully aware that many ohangezltv in the same may be made, Without departing from the spirit and scope of my invention, and do not, therefore, desire to be limited to the exact form of embodiment hereinabove described and shown in the accompanying drawings.

What I claim as new and desire to protect by Letters Patent, 1s-

1. The combination with the car, track.

A 2. The combination With tne car and track supporting structure of a monorail s tem7 of a laminated track upon the said struc Y ture, a rail secured to the said track, the said rail being of substantially U shape in cross section, and a single convex faced traction Wheel for the car.
